A'pplication filed April 26, 1916. Serial No. 93,5542

provements in Comover-Elbows, of which the following is a specification.

This invention relates m pneumatic conveyers for the conveyance ofashes, sand and other abrasive and disintegrated materials, and moreespecially to the conveyor conduit elbow carrying the nozzle for theintroduction of st mm or fluid under pressure to the conveyor conduitinterior.

An object of the invention is the etl'ectual and complete protection ofthe suction elbow against wear by the use of improved tubular wearliners. A further object is the provision of improved 11 cans toenablethe ready replacement of worn wear linerswithout the removal ofthe elbow itself from the conduit. line. A still furtherobject is theproduction of an elbow having an apcrtured wear liner through which thefluid under pressure is introduced. Other objects will be. mentioned anddescribed herein from time to time.

The preferred ei'nbodinient of the invention is disclosed in-theaccompanying drawings. wherein Figure 1 is a longitudinal section inelevation; Fig. 2 is a section on the. line 2-2 of Fig, 1; Fig. 3 is aview in side elevation of the cover plate in reduced sizc; Fig. l is aside view oi theelbow showing all wear liners and the cover plateremoved; and Fig. 5 a section showing a slight modification.

Similar numerals refer to similar members and parts of membersthroughout the several views on the drawings.

Referring tr the drawings in detail. the numeral 1 indicates the elbowbod provided with intake and discharge openings 2 and 3, respectivelythe former having the conventional flange 4. The numeral 5 indicates awear liner insertion opening formed in the side "of the elbow body andextending from a point therein adjacent the intake flange 4 around theelbow bend to a point intermediate. the. elbow bend terminus and the discharge openin The opening 5 is normally divided into the bend portion 6and the straight portion -'7, the latter being somewhat largerdiametrically than the portion 6. The numeral ,8 indicates the lateralflange of the insertion opening 5, substantially cothe elbow bendextensive therewith and provided. with the flat face, or surface, 9 thebolt holes 10,

10. The numeral 11 indicates a cover plate for sealing the opening 5 andadapted to be held in position against the face 9 by the bolts 12, 12detachablv engaging the flange 8.. The numeral 13 indicates a bossformed at the bend of the elbow exterior substantially midway thereofand provided with a nozzle aperture ll which is substantially in axialalinenient with the discharge opening 3. The numeral. 15 indicates anozzle for fluid under pressure. preferably steam, rigidly but detachabla rranged within the aperture 14. having its issuing: end substantiallyin axial alinemcnt with discharge opening and connected with pipe 16leading to a source of steam supp y.

The numeral 17. indicates a tubular removable weai liner at 'angedwithin the elbow bend at the intake and extending tor a fraction of thebond length to the end of the removable tubular medial liner 18. thelatter covering length. The numeral 19 indicates an inlet apertureformed in the outer wall ot the tubular liner il and in registry withthe boss aperturc ll to. permit the steam blast from the nozzle 15 toenter the elbow interior. The nunnt als 20 and 21 indicate. tubular wearliners removably arranged within the elbow enlargement and forward ofthe bend terminus. :h of which is somewhat thicker than the linermembers 17 and 18. To accommodate liner member 21 the elbow extensionbore is diametrically substantially the same as the enlargement T. Inmicration. the liners 20 and 21 take the impact of the steam blast andthe abrasive action of the materials cast or projected by the steambefore the latter is blown out of the discharge opening it therchvcausing excessive wear within the longitudinal limits of said wearliners. For this reason, it is desirable to thicken the liners 20 and 21to The liner 18- the cove:- plat= ll in position, the plate 11 is inposition, after tastening provided with tion 22, o a series l er, eachof winch thereof for ea engages a lnwr. obvious that other to for thisaccomt i n'icans may be resorted plislnnenl, such as a set. screw, orthe like. At Fig. 5 a plain nnaperiured liner 18 is shown for use whenthe elbow is utilized merely as a lined elbow and without the nozzle 15.
